<span>The length of a circle is equal to 2π * diameter/2, where π = ~3.14. In our case we have 2*(~3.14) = 6.28 meters. So the correct answer is C.</span>
(3) 8
Step-by-step explanation:
Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.
BC/AB = DE/AD
BC/10 = 12/(10 + 5) = 12/15 = 4/5
or
BC = 10(4/5) = 8
D. 53, 107
The pattern is multiplying the previous number by two and then adding one to it.
